Bicycle kickstand accessory

Abstract

The present invention is directed to a kickstand attachment which provides a substantially increased weight bearing surface area. The present invention permits the bicycle to remain in an upright position on soft surfaces or on a particulate surface without the kickstand penetrating the surface.

I claim: 
     
       1. A bicycle kickstand accessory for attachment to the terminal end of a conventional bicycle kickstand of an associated bicycle comprising: a base support member having a bottom surface of an area substantially larger than the area of the terminal end surface of the kickstand, said base support member including pivot means for defining a pivot axis disposed above said bottom surface and spaced laterally from the center of said bottom surface; and   a clamp member pivotally mounted to said base support member for releaseably securing said base support member to the terminal end of the kickstand, said clamp member including: A. a unitary body member comprising: (1) a constrictable opening for receiving the terminal end of the kickstand;   (2) a first mounting tab pivotally attached to said pivot means for pivotally mounting said base support member to said unitary body member, said first mounting tab extending outwardly from said opening; and   (3) a second mounting tab extending outwardly from said opening, said second mounting tab being formed of a pair of locking tabs; and     B. applied force means for forcing said pair of locking tabs relative to one another to constrict said opening, such that said bottom surface engages the ground for providing support to the kickstand for resting the associated bicycle in an upright position.     
     
     
       2. A bicycle kickstand accessory according to claim 1 wherein said bottom surface has an area greater than 1.76 square inches. 
     
     
       3. A bicycle kickstand accessory according to claim 1 wherein said opening forms a gripping surface for receiving in forced frictional contact an area of the outer surface of the terminal end of the kickstand; and wherein said applied force means is manually actuable for forcing said gripping surface in frictional contact with said area of the outer surface of the kickstand. 
     
     
       4. A bicycle kickstand accessory according to claim 3 wherein said opening is defined by at least a partial cylindrical surface of a size for receiving the kickstand; and wherein said gripping surface includes at least a portion of said partial cylindrical surface. 
     
     
       5. A bicycle kickstand accessory according to claim 4 wherein said unitary body member includes a split for defining said partial cylindrical surface. 
     
     
       6. A bicycle kickstand accessory according to claim 5 wherein said applied force means constricts said partial cylindrical surface. 
     
     
       7. A bicycle kickstand accessory according to claim 5 wherein said split includes an open slot disposed between said partial cylindrical surface and the outer surface of said clamp member; and wherein said locking tabs are located one on each side of said split. 
     
     
       8. A bicycle kickstand accessory according to claim 7 wherein said applied force means is a screw coupling said locking tabs for causing relative movement thereof by manually turning said screw. 
     
     
       9. A bicycle kickstand accessory according to claim 1 wherein said bottom surface of said base support member is circular. 
     
     
       10. A bicycle kickstand accessory according to claim 1 wherein said bottom surface of said base support member has concentric ridges. 
     
     
       11. A bicycle kickstand accessory according to claim 1 wherein said bottom surface of said base support member has radial ribs. 
     
     
       12. A bicycle kickstand accessory according to claim 1 wherein said bottom surface of said base support member has a rough textured surface. 
     
     
       13. A bicycle kickstand accessory according to claim 1 wherein said first mounting tab has a hole for pivotally mounting said base support member to said unitary body member. 
     
     
       14. A bicycle kickstand accessory according to claim 13 wherein said pivot means includes a pivot pin passing through said hole in said first mounting tab. 
     
     
       15. A bicycle kickstand accessory according to claim 14 wherein said pivot means includes a pair of mounting tabs for supporting said pivot pin. 
     
     
       16. A bicycle kickstand accessory according to claim 14 wherein said clamp member defines the disposition of the terminal end of the kickstand relative to the ground; and wherein said hole in said first mounting tab is located beneath the terminal end of the kickstand when said bottom surface engages the ground.
